SPECIFICATION forming part of Letters fPatent No. 510,734, datedDecember 12, 1893. Application filed Septeinlier 2t, 1893.. Serial No-486,469. iNo modem,

To all whom it may concern:

Be it known that I, ALBERT F. TRAGESER,

of the city, county, and State of New York,

have invented a neWand-Improved Appara tus for Distilling andConcentrating Glycerine and Heavy Oils, of which the following is afull, clear, and exact description.

The object of the invention is to providea new and improved apparatusfor distilling and concentrating glycerine and heavy oils,

and which is simple and durable in construcin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is asectional side elevation of-the improvement. Fig.2 is anenlarged sectional plan view of the condenser, on the 'line'2+-2 in Fig.l; and Fig. 3 i's-a similar view of the same on the line 33 of Fig. 1.

The improved apparatus is provided with the ordinary steel still A, setina furnace B of any approved construction, and provided with anagitator C driven by suitable means to agitate the liquid contained inthe still and fed therein through a pipe D from a suitable source ofsupply. a

On the lower end of the still A is arranged the usual removable head Efor-cleaning the still whenever necessary.

' From the upper end of the still A leads a pipe F to convey the vaporsarising in the still A to a condenser II, formed in:the upper end of ashell G containing below the condenser a receiver I and below the latteran evaporator J. The pipe F extends through the evaporator J and thereceiver I, and discharges into thelower end of the condenser H, thesaid pipe being provided at its upper end with a dash plate F to causethe vapors to be distributedin the lower end of the condenser. .Withinthelatter are arranged water cooling sections K, K each provided with awater inlet pipe K and each formed-withtransversely-extcnding-alternating partitions K so as to cause the waterto, circulate ward through the space formed between the outer edge ofthe section K' and the shell. The sections Kand K 1 are placed suitabledistances apart and from. the space between the sections lead branchpipes L' connected with a pipe ,L disposed vertically and dischargingat, its lower. end into the bottom of the receiver I. The pipe L isprovided with a valve L? for controlling the flow of the fluid from thecondenser to the receiver I. In the latter is arranged a coil'of pipeNhaving itsinlet end N connected with two valved pipes N and N of whichthe one is connected with afisteam supply, and the other with a coldWatersupply, so as to permit the operatorto forcecold or warm water orsteann,

through the coil of pipe N to heator cool the materialcontained in thereceiver I. The

lower end: of the latter is connected by apipe O with the lower end of;the evaporator J, and the said pipe 0 is provided with avalve O tocontrol the'fiow of the glycerine from the receiver I to the evaporatorJ. From the bottom of the .latter leads a valved pipe P for withdrawingthe finished product, and in the bottom of the evaporator is arranged asteam coil Q for evaporating the material. From the upper end of'thisevaporator J leads a flue R for carrying off the vapors, and into thispipe leads the outlet pipe 8 extending from the upper end of thecondenser H. The pipe S is provided near its entrance into the pipe Rwith an S-trap S and above the latter is arranged a valve S forconnecting or disconnecting the pipe S and the pipe R.

The operation is as follows: Theliquid subjected to heat in the still Areadily evaporates and the vapors pass up the pipe F to finally strikethe dash plate F so as to be distributed in the lower part of thecondenser II. The vapors circulate up in the condenser through andaround the several water cooled sections K and K so that the vapors arecondensed and pass tliirough the branch pipes L into the pipe L and fromthelatter flow downward into the lower part of the receiver I. In thisreceiver the glycerine or other product is kept at the propertemperature by regulating the flow of p the water or steam through thecoil of pipe N, and the glycerine can be withdrawn from the receiver tobe discharged into the evaporator J whenever the operator opens thevalve 0 in the pipe 0. The glycerine in the evaporator J is subjected tothe heat radiating from the steam coil Q and also to the heat radiatingfrom the pipe F through which the vapors pass up from the still to thecondenser, as previously described. The water vapors finally pass fromthe evaporator into the flue R to be carried to the usual roofcondenser, while the product remaining in the evaporator is drawn 01ffrom time to time by opening the valve P in the pipe P. The gases in theupper part of the condenser H can pass through the pipe S into thechimney flue whenever the valve S is opened, but any valuable productpassing with the gases through the said pipe S is caught in the trap S,and finally flows from thelatter into the pipe R and through the latterinto the evaporator J. The receiver serves asa storage reservoir as itpermits the condensed vapors coming from the condenser to accumulate andto re-fill the evaporator after the finished product of the previouscharge has been withdrawn from the evaporator J.

It is understood that the evaporator J is to be run under vacuum bymeansof the flue R and the roof condenser (not shown) connected with a vacuumpump. By opening the valve S in the pipe S then the condenser H, as wellas the receiverwill be run under vacuum, likewise the still A. A fan Tmay be employed in the pipe F to drive the va' pors upward from thestill into the condenser. It will be seen that by this arrangement theprincipal workin g parts are all confined within the shell G, so that acostly vacuum pan for concentrating purposes is not necessary, andfurthermore all the valuable products are completely saved.

It is understood that the still A as well as the evaporator J andreceiver 1, are provided with the usual thermometers, gages, 850.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent-- 1.
